Pengaruh Interval Pemotongan Rumput Brachiaria humidicola (Rendle) Schweick terhadap Konsentrasi Amonia dan Asam Lemak Terbang (In Vitro)

Abstract: The existence of weeds significantly depressed productivity and quality of herbage. Physically weed controlled by defoliation could be expected to sustain quality and production of herbage, and able to control weeds expansion. The aims of study were to find the effect of interval defoliations of B. humidicola that invited by C. odorata and its effect on concentration of ammonia and volatile fatty acid of B. humidicola herbage (in vitro). The experiment was carried out at Laboratory of Agrostology, Faculty of A… Show more

“…Increasing the age of plants and fertilizer levels followed by increased production of dry materials, organic materials and crude protein. Subagio and Kusmartono (1988) were quoted by Mansyur et al (2006) that the production of dry materials will increase along with cutting age [43]. In the old plants results of photosynthesis activity in addition to being used for growth is also stored as food reserves so that the content and production of dry material increases with age of cutting.…”

“…Menurut Mansyur dkk. (2005), ada kecenderungan perubahan produksi segar dan peningkatan bahan kering seiring dengan lama umur pemotongan dikarenakan proporsi bahan kering yang dikandung oleh suatu tanaman berubah seiring dengan umur tanaman.…”

“…Hartadi dkk. (2005) menyatakan bahwa nilai TDN dipengaruhi oleh kadar serat kasar, protein kasar, lemak kasar, dan BETN. Hasil komposisi kimia yang tinggi tersebut akan meningkatkan nilai TDN dari bahan pakan, sebaliknya apabila komposisi kimia bahan tersebut rendah maka akan menurunkan nilai TDN.…”

“…Menurut ) pada perlakuan produksi bahan kering. Hal ini di duga karena umur pemotongan tanaman yang terlalu muda menyebakan bahan kering pada penelitian ini tidak berpengaruh nyata, dimana produksi bahan kering meningkat apabila dosis pupuk nitrogen yang di berikan semakin tinggi dibarengi dengan umur pemotongan yang semakin lama Mansyur et al (2006). bahwa produksi bahan kering akan bertambah dengan bertambahnya umur pemotongan.KESIMPULANBerdasarkan penelitian di atas dapat disimpulkan bahwa dengan dosis Urea pupuk Urea 300 kg/ha setara dengan 0,75 g/polybag memberian pengaruh yang baik pada tinggi tanaman, jumlah anakan, produksi bobot segar pada rumput setaria (Setaria Spendida Staft) Sumarsono.…”
